Active Agent-Particle Combination Supporting Bone Regeneration

Dominique Pioletti, Ulrike Kettenberger

The invention provides for a bioactive composition comprising solid particles, such as e.g. calcium phosphate particles, loaded with an active agent, preferably an osteoconductive/osteoinductive agent or an anti-resorptive agent like a bisphosphonate. The ...

3D Printing of Polymers with Hierarchical Continuous Porosity

Dominique Pioletti, Pierre-Etienne Bourban, Matteo Gregorio Modesto Marascio, Jens Antons

Cellular thermoplastic structures with multiscale porosity (1–300 µm microporosity to 0.3–10 mm macroporosity) are produced from an integrated approach of 3D printing by Fused Deposition Modeling printing and Supercritical CO2 Foaming. Porous strands and r ...

Fabrication process of silicone-based dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Samuel Schlatter

This contribution demonstrates the fabrication process of dielectric elastomer transducers (DETs). DETs are stretchable capacitors consisting of an elastomeric dielectric membrane sandwiched between two compliant electrodes. The large actuation strains of ...

Study on Influence of Column Size and Slab Slenderness on Punching Strength

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

This paper presents the results of a systematic experimental campaign consisting of 13 symmetric punching tests on interior slab-column connections. The study focuses on the influence of varying the size of the supported area and the slenderness of the sla ...

Self-Healing Fiber-Reinforced Composites with Tailored Supramolecular Matrices

Federica Sordo

Fiber Reinforced Composites (FRCs), due to their intrinsic heterogeneity, are generally affected by complex multi-scale failure mechanisms leading to the formation of matrix cracks that are difficult to detect and repair. FRCs with the ability to heal and ...

Thermal mending in immiscible poly(epsilon-caprolactone)/epoxy blends

Véronique Michaud, John Christopher Plummer, Amaël Maximilien Cohades, Erica Manfredi

Blends of commercial epoxy monomer with a 4,4'-diaminodiphenylsulfone hardener and poly(epsilon-caprolactone) (PCL) were evaluated for their potential as a self-healing matrix for fiber-reinforced composites, based on their room temperature toughness and s ...

Curing kinetics and thermomechanical properties of latent epoxy/carbon fiber composites

Véronique Michaud, Pierre-Etienne Bourban, Sara Dalle Vacche

In this work, resins based on diglycidyl ether of bisphenol A (DGEBA) epoxy and a latent hardener, dicyandiamide (DICY), as well as carbon fiber (CF) composites based on them, were prepared with three commercial accelerators: a methylene bis (phenyl dimeth ...

Nano Fibrillated Cellulose Based Composite Hydrogels for an Injectable Intervertebral Disc Implant

Azadeh Khoushabi

Replacing the gel-like central part of the intervertebral disc (IVD), so-called nucleus pulposus (NP), via a minimally invasive surgery is one of the most recent approaches in the lower back pain treatments. An appropriate biomaterial for NP replacement (N ...
